Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 3 generators on 28 points:

(1,2,3,4)(5,6)(7,9)(8,10)(11,12)(13,14,18,16)(15,21,23,28)(17,25,26,20)(19,27,24,22);(5,6)(7,11,12,9)(8,10)(13,15,17,22,18,23,26,27)(14,19,20,21,16,24,25,28);(5,7)(6,9)(8,12)(10,11)(13,16,18,14)(15,19)(17,25,26,20)(21,22)(23,24)(27,28)
